Fan Casting Father Goose

During World War II, a man persuaded to live on an isolated island and spot aircraft finds himself responsible for a teacher and several students, all female. People tend to not want to remake Cary Grant films but I think there may be one or two greats who could pull off a role or two from that screen icon. My top two I would like to see try: Idriss Elba and Tom Hiddleston. So this is the movie, a great favorite of mine, I first thought of for Elba.
